摘要: 利用新疆2001、2010、2018年的MODIS遥感影像数据,对研究区的耕地、林地、草地、建设用地、水体和未利用地等土地利用类型,分别从土地利用/覆被幅度变化、转换矩阵等模型对研究区近18年的土地利用/覆被变化及驱动因素进行分析。结果表明,2018年新疆土地利用/覆被类型以未利用地为主,占研究期土地总面积的70.24%;其中耕地、草地、水体及建设用地面积分别增加了25 149.684、11 280.984、8 508.374、45.734 km2,主要由未利用地转入;林地、未利用地面积分别减少了1.97、44 838.024 km2;各土地利用/覆被类型之间存在不同程度的转换。研究区土地利用/覆被变化受到自然、社会、经济等因素的共同影响。

Abstract: Using the MODIS remote sensing image data in Xinjiang in 2001, 2010 and 2018, the land use types such as arable land, forest land, grassland, construction land, water area and unused land in the study area were studied via the models of land use/cover range change and transformation matrix to analyze the land use/cover changes and driving factors in the study area in the past 18 years. The results showed that, in 2018, the land use/cover types in Xinjiang were dominated by unused land, accounting for 70.24% of the total land area during the study period. The areas of arable land, grassland, water areas and construction land increased by 25 149.68, 11 280.98, 8 508.37, and 45.73 km2 respectively, which were mainly transferred from unused land; the areas of forest land and unused land decreased by 1.97, and 44 838.02 km2 respectively. There are varying degrees of conversion between land use/cover types. The land use/cover change in the study area is affected by natural, social and economic factors.
